Hi guys
I'm a noob and need help with some wiring in my motorbike. It involves a dual filament bulb and a set of horns.
About the bulb first:
The bike has two 35/35W dual filament bulbs. The one on the left has all three wires going in (high beam, low beam and ground) but there's no low beam wire to the other bulb. So when I need light from both bulbs I have to turn on the high beam which sometimes creates problems for other road users. I wish to have low beam on the right side as well. The plan is to have a branch wire from the low beam wire of the L bulb, connect it to a relay and power the low beam filament of the R bulb with a fresh line from the battery.
And now the horn.
The bike currently has a single horn which I think is rated at around 3.5 amps. It produces the old 'meep' sound which sometimes doesn't catch people's attention. I wish to replace it with a 2A+2A dual horn set using the typical relay circuit.
Please see the planned wiring diagram and suggest any changes that might be required.
I have a few doubts.
1. I'm using a single live wire and ground wire to connect both devices in a parallel circuit. Would a thick wire (like gauge 10) handle the job? Please do note that the horn circuit would only work for a short period of time and I don't know if there would be enough space for separate wires in a small 3.5Ah battery terminal.
2. How much current does a relay typically draw to turn the main circuit on? Would it affect the performance of the lender circuit in any way?
3. What would be the best way to get the supply wire from the L bulb circuit? It has a spade connector at the end. I don't have any splitter to attach to it so I'm thinking why not remove the insulation at a segment of the wire and connect from there.
4. What should be the ideal fuse rating for a circuit like this. The total load is (2x2) + 3 = 7A. The horn is rated at 2A. Is it the maximum current the horn will draw at any point in time?
5. Would grounding to the chassis give me any advantage? It's something I've never done or seen in real life. The distance from the devices to the battery is around 1m. The bike has a powder coated frame.
